Make methods static when they are not part of the instance. Don't sweat the micro-optimisations.
You might find you have lots of private methods that could be static but you always call from instance methods (or each other). In that case it doesn't really matter that much. However, if you want to actually be able to... |
Whether or not a method is static is more of a design consideration than one of efficiency. A static method belongs to a class, where a non-static method belongs to an object. If you had a Math class, you might have a few static methods to deal with addition and subtraction because these are concepts associated with Ma... |
In the end it all boils down to the protocol you'd want to use. Shoutcast IMHO is plain HTTP, so to *make* your own stream, you just output the streams content.

The best strategy is always to give your users options. Why don't you start the stream at a low bitrate that will work for everyone and provide a "High Quality" link for those of us with FTTH connections? I believe YouTube has started doing this. |

I don't think it will become mainstream. I think Ted Dziuba gets it right when he says it solves a "problem" that most people don't consider to be worth solving.

If it were me, I'd reverse the question and ask why *I should* use a GridView, If you need a bunch of built-in features like paging and sorting, then the GridView might be a good fit. If you just want tabular data, I'd reconsider. Why? Because with GridView you're getting a whole bunch of stuff you won't use, your ... |
Try attacking it from the other angle. Look at streaming services that cater to the customer you want, and have significant volume (maybe youtube) and see what they're pushing. You'll find there'a pretty direct correlation between alexa rating (popularity) and quality(minimum bitrate required). Vimeo will always hav... |
In your above scenario, you'd be better off doing a master-detail style GridView, which will save you the overhead of all those GridView objects that get created.

The cause of your problem is **NOT** the Win console not willing to accept Unicode (as it does this since I guess Win2k by default). It is the default system encoding. Try this code and see what it gives you:
